Chapter 9 Troubleshooting
Reverse (CWL) limit switch error
:
Potential Cause
Reverse limit switch is
activated.
Servo system is not
stable.
Forward (CCWL) limit switch error
:
Potential Cause
Forward limit switch is
activated.
Servo system is not
stable.
IGBT temperature error
:
Potential Cause
The drive has exceeded
its rated load during
continuous operation.
Short-circuit at drive
output.
Memory error
:
Potential Cause
Parameter data error
when writing into EE-
PROM.
The setting value of
hidden parameter is in
error.

Checking Method
Check if reverse limit switch is On or Off. Activate reverse limit switch.
Check the value of control parameter
setting and load inertia.
Checking Method
Check if forward limit switch is On or Off. Activate forward limit switch.
Check the value of control parameter
setting and load inertia.
Checking Method
Check if there is overload or the motor
current is too high.
Check the drive input wiring.
Checking Method
Examine the parameter settings. Please
do the following steps:
1. Press SHIFT key on the drive keypad,
and examine the parameter shown on
LED display.
2. If E320A is displayed (in hexadecimal
format), it indicates it is parameter P2-
10. Please examine the parameter
settings of P2-10.
3. If E3610 is displayed (in hexadecimal
format), it indicates it is parameter P6-
16. Please examine the parameter
settings of P6-16.
Press SHIFT key on the drive keypad
and examine if E100X is displayed on
LED display.
Corrective Actions
Modify parameter setting and
re-estimate motor capacity.
Corrective Actions
Modify parameter setting and
re-estimate motor capacity.
Corrective Actions
Increase motor capacity or
reduce load.
Ensure all wiring is correct.
Corrective Actions
1. If this fault occurs when
power is applied to the drive,
it indicates that the setting
value of one parameter has
exceeded the specified range.
Correct the setting value of
the parameter to clear the
fault and restart the servo
drive.
2. If this fault occurs during
normal operation, it indicates
that the error occurs when
writing data into EE-PROM.
Turn ARST (DI signal) ON to
clear the fault or restart the
servo drive.
If this fault occurs when
resetting the parameter settings,
it indicates that the servo drive
type is not set correctly.
Correctly set the servo drive
type again.
